Answer:
Option B.
Step-by-step explanation:
Consider the below figure attached with this question.
From the below figure it is clear that the center of the given circle is (4,5).
The standard form of a circle is
where, (h,k) is center of the circle and r is radius.
We need to find the equation of a circle which represents the same center as the circle shown but with a radius of 2 units.
Substitute h=4, k=5 and r=2 in the above equation.
The required equation is .
Therefore, the correct option is B.
The order from least to greatest negative four and seven tenths repeating, negative four and eight ninths, 490%, and −4.9 from least to greatest is; option A
- −4.9,
- negative four and eight ninths
- four and seven tenths repeating
- 490%,
<h3>Ascending order</h3>
four and seven tenths repeating
= 4.77777777
negative four and eight ninths
= -4 8/9
= -4.888888888888888
490%
= 490/100
= 4.9
−4.9
Rearranging from least to greatest (ascending order)
- -4.9
- -4.888888888888888
- 4.77777777
- 4.9

Negative numbers don’t have real square roots since a square is either positive or 0
Answer:
Segment addition postulate
Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
= k , that is
k = 
y = xz ← equation of variation
When x = 2 and z = 3 , then
y = × 2 × 3 = 5 × 2 = 10
